−	~~The technical design stage is sometimes referred to as ‘Design’.~~	+
−		+
−	Technical design develops the design in sufficient detail for co-ordination to be completed and enables packaged, production information to be prepared which can be passed to the contractor and their supply chain to construct the development. It should also allow applications for statutory approvals to be completed.<br/>	+
−		+
−	The word 'supplier' is used in this stage to refer either to an integrated supply team if a supplier has been appointed to design and construct (and perhaps operate) the proposed development, or to refer to design consultants if suppliers have only been appointed to design the proposed development at this stage. Increasingly, technical design also involves design undertaken by specialist subcontractors.	+

−	The supplier co-ordinates the appointment of specialist subcontractors to assist in the preparation of the technical design. This should include an assessment of their BIM and IT capability and capacity, which may reveal the need for training. It may be appropriate to arrange visits to the specialist subcontractors' premises to assess samples or mock-ups and to witness tests.<br/>	+
−		+
−	~~If they do not already have one, the supplier should appoint a design co-ordinator with specific responsibility for co-ordinating and integrating specialist subcontractors' designs.<br/>~~	+
−		+
−	Specialist designs should be incorporated into the developing building information model and generic objects progressively replaced with specific objects with specifications and method statements attached along with information about space allocation for operation, access, maintenance, installation, replacement and so on. This may require a 'change of ownership' procedure for those parts of the model.	+
−		+
−	~~Clash detection simulations should be undertaken.<br/>~~	+
−		+
−	Model simulations may be undertaken to demonstrate compliance with remaining building regulations and other statutory approvals (such as structural performance, energy use, acoustic performance, fire and smoke modelling, evacuation modelling and so on).	+
−		+
−	Packages of work should be identified and critical interfaces highlighted. Production level objects with embedded specification should be developed that will allow tenders to be obtained from contractors (or their supply chain if the contractor has already been appointed) and may be used for fabrication, co-ordination, sequencing and estimating.	+
−		+
−	There should be a particular emphasis on equipment with long manufacturing times such as; switchgear, chiller units, lifts, escalators and bespoke cladding systems, some of which may justify early ordering. In addition, there may be front-end construction work such as; service diversions, demolition, setting out , underground drainage, piling and other groundworks that merit placing preliminary contracts.	+
−		+
−	The construction sequence should be developed in detail and may define crane zones and lifting operations, formwork, access details, construction sequences and movements, logistics and so on, linked to a project management scheduling tool to co-ordinate the works.	+
−		+
−	The elemental cost plan should be developed into an approximate quantities cost plan which may be taken off from the model, accompanied by a schedule of assumptions made and a cash flow projection. A pre-construction whole-life cost plan may be prepared. If necessary a value management exercise maybe undertaken.	+
−		+
−	~~An end of stage report is prepared identifying key issues as well as details of packaging, long lead time items and preliminary contracts.~~	+
